Teak in a bathroom?

Is teak a viable choice for a bathroom? I mean, it was used for battleship decks , it should hold up pretty well I would think. They say hardwood in a bathroom is not good but I thought that teak was the all weather tough stuff. Or am I missing something important?

you could install a trench style floor drain (with teak floor installed above) and use this product by Schluter to direct any water that gets under the finish floor to the floor drain. You'd have to install a water proof membrane over your subfloor, something like Kerdi. attach teak boards to cross members underneath so that finish floor would not have to be nailed/screwed to the subfloor.

Of course this requires more detail to your work and expense. If it was me, I'd go with the wood finish tiles.

I have looked at those trench style drains....love the look....but to me to big concern would be moisture under the wood. Even with proper drainage, how would you keep the teak from staying wet underneath all the time?

I once did a bathroom floor with ipe. We blind-nailed through the tongues and used a generous amount of silicone around the perimeter between the wall and the expansion gap, and trimmed out with baseboard milled from ipe. The floor was finished with 5 coats of spar varnish. The clients recoated with more varnish a couple of times since the install.
The floor has been down for 12 years and still looks great. The spar varnish really seals well and makes the grain and colors in the ipe come to life.
I would not hesitate to use teak in the same way. As long as your subfloor is cdx plywood or better, Advantech, etc I don't think you'd have a problem.

Yes I was just talking about outside the shower. I have no motivation to deal with any drainage issues or anything crazy. I will be replacing the subfloor also so I will hopefully make it so it supports tile. I have never done a floor before and was just wondering why it wasn't advisable. It makes sense now.
